Why do we still need to invalidate string theory? It was never validated. There is a problem with gate keepers in physics.

I read Kaku's Hyperspace in 1996. He explained everything there, and the same damn problem existed back then. Lol

Of all the luminous guests appearing on this podcast, I find myself returning to Peter Woit’s episode the most. The questions Lex asks and the answers Peter provides are remarkably edifying. Well done!

[solefood]

Is that Lex Grossman!!!??? This is the Lex X Lex crossover we never knew we needed!!

[pwillreal]

He’s not the only one saying it’s dead

[WanderingIdiot]

I haven't even heard anyone talk about string theory in like ten years

[sistajoseph]

The problem of dimensions do not exist in physics. What is a dimension. A dimension is only an independent variability of a phenomena. Eg, if we find out today in the description of matter, they is spin and spin does have a known source, then spin is a dimension and so on.

[dgeesiogaming]

what hes basically doing is trying to work out like a programmer the meaning of life.

If I come up with an equation that tells me 3+1 = 10, I say it's wrong. If a tenured physicist gets the same answer he gets to pretend the 10 is a 4?

String Theory isn't flawed ... it has too many solutions, with nearly all being incompatible with our universe. In the meantime, quantum mechanics is incomplete AND an approximation.

[Rakscha-Sun]

8:15 So if the experiment to proof the theories don't show this extra dimensions you just say the dimensions are much smaller till you reached a scale where not even the best scientific instruments measure anything and that than proofes that string theory could work...

That is a nice way of saying it is absolute unfalsifiable garbage.

[jacklatta]

The greatest problem with string theory…is that you look at a competent theoretical physicist, trying to explain it simply, and they show it on their face…even THEY don’t have a clue what they are talking about…like a group of people who can add and subtract on paper, but can’t justify why this is even relevant…even if it unifies the 2 theory’s…ok, what does this do for me? I’m happy that you can do this math on paper, now, what does the “7th dimension do?” “What does the 8th serve?” Why is the 9th dimension RELEVANT, besides justification of your equations???

[oisnowy]

Of course string theorists never consider the most likely and most realistic and certainly the most simple reason why certain things do not seem to occur in nature despite string theory begging for it to exist...

[endofdaysprophet]

Peter Woit cannot explain his arguement!!! He basically is saying I don't understand therefore it is wrong. I see nothing that creates 10 dimensions 4 is all there is and all that is needed!!!

Dimensions only exist in relation to something, like time. The question is, do they really exist ? Maybe not. Simulation theory is the closest and best thing we have to how it works.

What does Laura Croft see inside her video game world? - a world with 3 dimensions and 1 of time. But what is her world really ? It’s just information, somewhere on a hard drive… Our universe works exactly the same way.. it’s very simple. Space and time are illusions and the universe is a hologram, based on information. The more pieces you pick apart the more pieces there are to pick apart.

Black holes are the equivalent of hard drives. Everything in a given galaxy 🌌 resides in two places at once. One in local space-time coordinates, and another as information on the accretion disc of the supermassive black hole in the galactic core.

[spsmith]

Could we get rid of the six extra dimensions by adding two time dimensions to our existing 3+1 dimensions. Two more time dimensions times the 3 spatial dimensions gives 6. Maybe those are the six dimensions we are looking for? 3 time and 3 space dimensions does have a certain symmetry. Just like a 3-D vector in space can be viewed as a single dimensional line, a 3-D vector in time could be perceived as a single dimensional time dimension. I'm sure this has been explored and dismissed. Any theoretical physicists out there who can chime in?

This video left my string theory in tangles . . .

I just want to go back to the Berenstein universe
